Washington Wrote a Letter to the Continental Congress
March 24, 1776
You can learn a lot from reading old letters. Fortunately for Americans interested in the country's early history, George Washington was a talented and frequent letter writer. On March 24, 1776, General Washington wrote a letter to the Continental Congress (the governing body of the American revolutionaries). In it, he described how he had made the city of Boston safe from future attack by the British, but that the mischievous British fleet would not leave the Boston harbor. It was his second letter to Congress about the attack on Boston.
